Constructor
Variables
read onlycurrentTime:Float
Returns a double representing an ever-increasing hardware time in seconds used for scheduling. It starts at 0.
read onlydestination:AudioDestinationNode
Returns an AudioDestinationNode representing the final destination of all audio in the context. It can be thought of as the audio-rendering device.
An event handler that runs when an event of type statechange has fired. This occurs when the AudioContext's state changes, due to the calling of one of the state change methods (AudioContext.suspend, AudioContext.resume, or AudioContext.close).
read onlysampleRate:Float
Returns a float representing the sample rate (in samples per second) used by all nodes in this context. The sample-rate of an AudioContext cannot be changed.
